From dd8dd300c636bf0a1352379aed88d9434a6ac7bb Mon Sep 17 00:00:00 2001 From: Ævar Arnfjörð Bjarmason Date: Tue, 13 Nov 2018 19:52:43 +0000 Subject: push: add an advice on unqualified push MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add an advice to the recently improved error message added in f8aae12034 ("push: allow unqualified dest refspecs to DWIM", 2008-04-23). Now with advice.pushUnqualifiedRefName=true (on by default) we show a hint about how to proceed: $ ./git-push avar v2.19.0^{commit}:newbranch -n error: The destination you provided is not a full refname (i.e., starting with "refs/"). We tried to guess what you meant by: - Looking for a ref that matches 'newbranch' on the remote side. - Checking if the being pushed ('v2.19.0^{commit}') is a ref in "refs/{heads,tags}/". If so we add a corresponding refs/{heads,tags}/ prefix on the remote side. Neither worked, so we gave up. You must fully qualify the ref. hint: The part of the refspec is a commit object. hint: Did you mean to create a new branch by pushing to hint: 'v2.19.0^{commit}:refs/heads/newbranch'? error: failed to push some refs to 'git@github.com:avar/git.git' When trying to push a tag, tree or a blob we suggest that perhaps the user meant to push them to refs/tags/ instead. The if/else duplication for all of OBJ_{COMMIT,TAG,TREE,BLOB} is unfortunate, but is required to correctly mark the messages for translation. See the discussion in <87r2gxebsi.fsf@evledraar.gmail.com> about that.
